Smart. Let Smart Albums automatically create albums tailored for you. Smart Albums intelligently populate albums based on tags, ratings, date taken, image size, and much more. Just set up a simple rule such as images with the tag “Family” or videos with a 5-star rating. We take care of the rest by creating an album that updates as your library grows.
Simple. We know how frustrating it is trying to find the image you just saved, so we do it for you. Our simple tools allow you to instantly find your images and display them with crystal clarity.
Crystal clear. Pixel perfect. Don’t sacrifice quality because you went mobile. Enjoy your high resolution images in crystal clarity. Go ahead. Zoom in as much as you like.
Your Taste. Your Style. Every person has a unique taste. Choose one of our beautiful themes to express your very own style. We provide you with a predefined set of gorgeous color themes to bring you the best experience and to make sure that the user interface remains in harmony.
